Bronze distributor shaft gear wear
Oil pump/intermediate drive shaft Bushing install
It is not a given that you will have to burnish/ream the new one, the Durabond version. I’ve installed them in two different engines recently and that step was not required. (I also use some green Loctite bearing retainer for good measure) Some may say that’s pure luck not having to burnish/ream.. Whatever, it didn’t need doing in both my cases. I use an old intermediate shaft to tap the new bushing into place. You might be able to use a slide hammer and use a blind bushing puller (I think that’s what its called) or as mentioned above to pull the old one.
